Interest rates have been volatile in 2025, which has resulted in directionally offsetting monthly impacts in the MRB asset (liability) rollforward. These offsetting monthly impacts resulted in a net favorable impact from interest rates to the net MRB asset (liability) for the six months ended June 30, 2025, despite a small decrease in the weighted-average long-term interest rate input.

(1)The weighted-average attained age is calculated at the contract level using the total contributions since inception and the age of the contractholders.
(2)The net amount at risk for our GMDB riders is defined as the current GMDB amount in excess of the current account balance. The net amount at risk for our GMWB riders is defined as the greater of the present value of the GMWB payments less the current account balance or zero. For contracts with both GMDB and GMWB riders, the net amount at risk is the greater of the GMDB or GMWB net amount at risk. We had a decrease in the net amount at risk in 2025 primarily as a result of increases in the equity markets.
